A Fault status is indicated by a yellow LED and also by

the 4-20 mA outout. Refer to Table 6 to identify the fault

type using the 4-20 mA output. (The operator must know

which fault signaling mode has been programmed.)

Refer to Table 7 for assistance in correcting malfunctions

with the PointWatch Eclipse Detector.

The Pointwatch Eclipse IR Hydrocarbon Gas Detector is

not designed to be repaired in the field. If a problem

should develop, first carefully check for proper wiring,

programming and calibration. If it is determined that the

problem is caused by an electronics failure, the device

must be returned to the factory for repair.

Prior to returning devices or components, contact the

nearest local Detector Electronics office so that a Service

Order number can be assigned. A written statement

describing the malfunction must accompany the returned

device or component to expedite finding the cause of the

failure.

Return all equipment transportation prepaid to the factory

in Minneapolis.
